which transformation represents a reflection over the y = x line?
a. (x, y) → (−x, y)
b. (x, y) → (−x, −y)
c. (x, y) → (y , x)
d. (x, y) → (y, −x)

a.

Step-by-step explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

answer: it is d
